LAB15 – Feedstock-Lab

The BinderJetting process (BJT) can be used to produce complex components from a wide range of materials cost-effectively and efficiently. In order to exploit the full potential of BJT, a comprehensive characterization of the starting materials, the so-called feedstocks, is essential due to the strong interactions along the process chain. This allows important material properties, such as particle size, specific surface area or droplet size, to be analyzed. These measured variables enable targeted adjustment of the process parameters in order to optimize the quality of the printed components and tap further potential.

Aim, approach and benefit

The aim of the project is to set up a laboratory for characterizing and optimizing the starting materials for the BinderJetting process in order to exploit its full potential. The laboratory is made up of a total of four components:

1. Measuring instrument for the characterization of particles in the micrometer range
2. Measuring instrument for the characterization of particles in the nanometer range
3. Measuring device for the determination of the specific surface of particles
4. Dropwatcher for characterizing the binder droplets and adjusting the nozzle control of the printhead

The planned procurements are not only of interest for the BinderJetting process, but also offer great synergy potential with other additive manufacturing processes. Further research activities in the field of additive manufacturing will therefore also benefit sustainably from this laboratory.
